other doubt
https://github.com/MariaDB/server/blob/10.1/storage/oqgraph/ha_oqgraph.cc#L462
when using aria as backstorage, aria engine don't support insert delayed,
this will make some problems not?


about query cache i didn't found a register_query_cache_table function like
aria/innodb/myisam engines, maybe we should change documentation to 'query
cache isn't supported with oqgraph' instead of 'needs to be disabled'
